SECTIONAL R/SILIENT TIRE.

Specification of Letters Patent.

Application filed Mareh; 1912. Serial No. 682,768.

To all 'idiom it 'muy Cof/werfe Ylie it known that l', CHARLES A. MARIEN, a eitizen of the United States, residing at St.

Louis, ll'lissouri, have invented a certain new and usoi'ul Sectional Resilient rl`ire, of which the :tollowingn is such a Jfull, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the saine, reference beine; hadto the accompanying drawings, forming part of this speci iie ation.

lily invention relates to a sectional resilient lire and more particularly to one eonsisting oi' two sets of resilient blocks which are arranged side by side so that the joints between one set of bloelrs are out i alineinent with those between the other set ot' bloeks.

',lhe object of my invention is to provide means for detaehably securing the resilient blocks in position on the periphery of the wheel.

ln the accompanying drawings, which illustrate one :torni of tire made in aeeordanee with my invention, Figure 1 .is a, side elevation of a portion oft the Wheel; Fig. 2 is a top plan View; Fig. 3 is a section taken on the line or Fig. 2; Fig. l is a side View of one oit the bloelrs, partly in section and partly in elevation; Fig, 5 is a perspective View or" one or the outer retaining" members and 6 is a perspective View of one of the central retaining members.

.liilre marks ot reference rel'er to similar parts in the several views or the drawings.

10 represents the spokes olf the Wheel which Carry a telly 11 of any suitable form. r.lfhis :telly 11 is surrounded by a telly band '12 u'hieh projects laterally beyond the telly 11 at both sides as best shown in Fig. 3; 18 represents the sectional blocks of rubber or other suitable resilient material. These bloelrs 13 are arranged in two sets as best shown in Fig.

These end extensions 29 abut firmly against each other when the bloeks are in position and thus prevent the separation ot the hard and soft rubber` which might take place if this extension were not used. W'hile I prefer to form the projections in this manner, l

do notr desire to limit my invention t -sueh Construction as the projections may loev formed in any suitable manner, such to'r eX- ample as is shown in my prior latent, No. 979,869, granted to me December 27, 1910.

ln order to secure the bloeks in position on the periphery ot the Wheel, I provide a number ot outer retaining members 17 shown in detail in Fig. 5, and a number of central retaining members 18, shown in detail in Fig. G. Each of the outer retaining' members 17 is provided with a pair of pockets 1f) adapted to receive the projections le at the outer sides of the resilient blocks 13. l

The retaining members 17 are held in position on the periphery' of the wheel by means of bolts E20 passingthrough openings 21 in the set of blocks 17 and through open4 ings in the projecting edges ol" the telly band 12. The inner ends of the bolts Q0 are engaged by nuts 22. Each ot' the inner retaining members 18 is proi'ided on one side 'with a pocket 23 for engaging one ot the Aprojeetions 14, and on the other side with a pair of pockets 951., also torengaging the projections 141. llt Will be seen that the inner blocks 18 are so shaped that they overlap A each other and each member is arranged with its single pocket at the opposite side to the member preceding aud the one sueeeeding;` it. The members 1S are held in position by bolts passing through oj'ienings QG in the said inenibers and through the tel ly band and telly. The inner ends of the bolts Q5 are engaged by nuts 27.

It will be evident that by .means of my Construction, a simple aud ei'ertive method of holdingr the staggered bloelgs in position attained, and, at the saine time, any bleek may be rapidly removed and replaced by a new onel by simpl;7 1ni;';ereWinagl the nuts 22 and 1i" which hold the retaining members in engagement with that particular bloek. The arrangement is also sueh that the spaces between the -`/arious blocks 13 may be reduced so as to cause no jar es the Wheel passes :from one block to another. '.ln order to prevent netting of the block 55 by the retaining members 1'? and 18, I prefer to slightly bevel the inner edges of the members 17 and both edges of the members 18, as is shown in Fig. 3 of the'drawings.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

l. The combination with a wheel, of a double row of resilient sectional blocks provided with lateral projections, retaining members arranged at the outer edge of each set of blocks and engaging with the projections, overlapping retaining members arranged between the sets of blocks and also engaging with the projections, said latter retaining members being each provided with pockets on both sides, the pockets on one side being greater in number than those on the other side, and means for securing said retaining members to the periphery of the Wheel.

2. The combination with 'a wheel, of a double row of resilient sectional blocks provided with lateral projections, retaining members arranged at the outer edge of each set of blocks and engaging with the projections, overlapping retaining members arranged between the sets of blocks, and also engaging with the projections, said latter retaining members being each provided on one side with one pocket and on the oppositeside with two pockets, and means for securing said retaining members to the periphery of the wheel.

ln testimony whereoi'l have hereunto set my hand and affixed my seal in the presence ot the two subscribing witnesses.
